Primakoff Lecture: “From Nonlinear Optics to High-Intensity Laser Physics”

Donna Strickland (University of Waterloo)
- David Rittenhouse Laboratory, A8

The laser increased the intensity of light that can be generated by orders of magnitude and thus brought about nonlinear optical interactions with matter. Chirped pulse amplification, also known as CPA, changed the…



High Energy seminar: "Black hole Love story"

Ram Brustein (Ben-Gurion University)
- David Rittenhouse Laboratory, 3C6

The response of a gravitating object to an external tidal field is encoded in its Love numbers, which identically vanish for classical black holes in 4 spacetime dimensions. I will explain why for quantum…



Thesis Defense: "DEVELOPMENT OF MUSTANG-2: A MICROWAVE SQUID MULTIPLEXED TES ARRAY FOR 90 GHZ IMAGING"

Sara Stanchfield (University of Pennsylvania)
- See Zoom link below

Galaxy clusters provide rich astrophysical laboratories with which to study some of the most energy event since the Big Bang. The myriad of important astrophysical phenomena that are present in these high energy…



Astrophysics seminar: "Characterizing Distant Worlds: Atmospheric Observations of Exoplanets with Hubble & JWST"

Munazza Alam (Carnegie Earth & Planets Laboratory)
- David Rittenhouse Laboratory, 4C6

In the past two decades, we have discovered thousands of planets outside of the Solar System, many of which are nothing like our own. We can learn a great deal about the properties of…



Condensed and Living Matter Seminar: "Semiconductor moiré materials: a new platform for strong correlation and topology"

Jie Shan (Cornell University)
- David Rittenhouse Laboratory, A8

When two van der Waals materials of slightly different orientations or lattice constants are overlaid, a long-wavelength moiré pattern emerges. In semiconductors or semimetals, the low-energy physics can…



Elon Musk Public Lecture: "Cosmic Inflation: My journey to the edge of science"

Andreas Albrecht (Department of Physics & Astronomy, UC Davis)
- Bodek Lounge, Houston Hall (HH100)

In 1982, while a grad student at Penn, my advisor and I wrote a paper that has since become very famous.



Experimental Particle Physics seminar: “EXO-200 recent results and nEXO outlook”

Michelle Dolinski (Drexel University)
- David Rittenhouse Laboratory, 2C8

The discovery of neutrino mass is direct evidence of physics beyond the Standard Model. It is an experimentally open question whether neutrinos have Majorana masses, and neutrinoless…



Thesis Defense: "Criticality in Eternal Inflation and Superfluidity"

Guram Kartvelishvili (University of Pennsylvania)
- David Rittenhouse Laboratory, 4N9



Condensed and Living Matter Seminar: "Magnetooptical properties of superconducting Nb thin films in the terahertz region"

Jae Hoon Kim (Yonsei University)
- David Rittenhouse Laboratory, A4

We studied the pair breaking effect of an external magnetic field up to 7 T on the type-II superconductor niobium (Nb) using terahertz time-domain spectroscopy at 1.5 K. Our measurement technique can…



CAMIPM seminar: "Non- and minimally- invasive Diffuse Optical Monitoring of Central Nervous System Hemodynamics"

David R. Busch, Ph.D. Department of Biomedical Engineering, University of Texas Southwestern)
